“…They are silicon diode detectors of 45`Â 45`Â 10 mm 3 external dimensions specially designed to measure personal dose equivalent H p (10) at interventional environment and to provide cumulative dose and dose rate (averaged on a second) (17,18) . Dosemeters are linked wireless to a base station, where the H p (10) (20,21) .…”

The purpose of this paper is to test the appropriateness of OSL and electronic dosemeters to estimate eye lens doses at interventional cardiology environment. Using TLD as reference detectors, personal dose equivalent was measured in phantoms and during clinical procedures. For phantom measurements, OSL dose values resulted in an average difference of 215 % vs. TLD. Tests carried out with other electronic dosemeters revealed differences up to + + + + +20 % versus TLD. With dosemeters positioned outside the goggles and when TLD doses were >20 mSv, the average difference OSL vs. TLD was 29 %. Eye lens doses of almost 700 mSv per procedure were measured in two cases out of a sample of 33 measurements in individual clinical procedures, thus showing the risk of high exposure to the lenses of the eye when protection rules are not followed. The differences found between OSL and TLD are acceptable for the purpose and range of doses measured in the survey.

“…DoseAware PDMs have been calibrated against thermoluminescent dosimeters and showed a 10%-15% difference in measurements. 8 When ED to the individual was desired, it was calculated by multiplying the deep dose equivalent by 0.30 according to the Webster methodology. 9 When personnel left the room (eg, for a lunch break) and were relieved by another individual, the PDM was transferred to that individual; thus, PDM data reflected the dose an individual would receive if present in the same role for the entirety of a case.…”

Personnel doses were best correlated with KAP and less well correlated with fluoroscopy time or CAK. The dosimeter on the anesthesia equipment recorded the highest doses attributable to ineffective shielding. Operators can reduce the effective dose to themselves, the patient, and other personnel by minimizing the use of digital subtraction acquisitions, avoiding lateral angulation, using higher magnification levels when possible, and being diligent about the use of shielding during fluoroscopy cases.

“…Routine monitoring of occupational dose (OD) is based on passive dosimeters, accumulating staff dose merely on a monthly basis. Active personal dosimeters (APD) can give a real‐time indication of the dose received . Recently, a system that integrates APDs with interventional x‐ray modalities became available, providing a direct digital link between the tube exposure settings, the geometric positions of the C‐arm, and both staff and patient radiation exposures.…”

The new x-ray and image processing technology, significantly reduces patient dose in coronary angiographies, and PCIs by 67%. In general, scatter dose was also reduced, yet for some dosimeters the reduction was limited and not statistically significant. This study clearly indicates that the scatter behavior is highly dependent on C-arm rotation, operator movement and height, dosimeter position, beam filtration, clinical procedure type and system geometry.
